Getting hands-on with Amazon SageMaker notebook instances The very first step, in this section, is to create a Jupyter Notebook, and this requires a notebook instance. You can start by creating a notebook instance, as follows: Figure 9.3 – Amazon SageMaker role creation sh-4.2$ cd ~/SageMaker/ sh-4.2$ git clone https://github.com/PacktPublishing/AWS-Certified-Machine-Learning-Specialty-MLS-C01-Certification-Guide-Second-Edition.git Figure 9.4 – Jupyter Notebook […]

The Route Table and Network ACL Tabs The Route table and Network ACL tabs allow you to view the associated route table and NACL with the subnet and make changes as necessary. The following screenshot shows a default route (local) with another route pointing to the NAT gateway. The NAT gateway handles internet requests (0.0.0.0/0) […]

AWS CloudFormation Another option for deployment is to use AWS CloudFormation. CloudFormation is a service that lets you provision all sorts of AWS resources, offering an IaC approach. You define your resources in one or multiple templates, written in either YAML or JSON. YAML is typically easier and less verbose, compared to JSON, for humans […]

ExamAlert You must be capable of reading and interpreting flow logs and identifying source IP and destination IP addresses, ports, and whether the traffic was blocked or allowed. Also, you need to understand that traffic can be blocked by a network access control list, and that the NACL is enforced before the security group on […]

Coexistence of the golden record Similar to the consolidated golden record implementation method briefly explained previously, MDM changes can happen in both the golden record system and any source system for master data. While this approach can take longer to implement, data can be mastered in the golden record system or any of the master […]

Trigger.isBefore, Trigger.isAfter These context variables provide information about the timing of the trigger execution. These variables are contained in the System.Trigger class and are commonly used to control the flow of logic within triggers. •\ Trigger.isBefore: Returns true if the trigger was fired before any record was saved. This variable is often used to perform […]

var blocky = “”” squirrel \s pigeon \ termite”””; System.out.print(blocky); var num1 = Long.parseLong(“100”); var num2 = Long.valueOf(“100”); System.out.println(Long.max(num1, num2)); public class Price { public void admission() { INSERT CODE HERE System.out.print(amount); } }

OSPF Areas An area is a logical division of routers and links within an OSPF domain that creates separate subdomains. LSA flooding is contained within an area, and the link-state database is limited to links within the area, which reduces the CPU and memory requirements for an OSPF-enabled router. You can assign an area ID […]

Subnets Selecting Subnets from the left-hand menu will bring up all the subnets associated with a particular VPC. If you do not have VPC filtering on, then all subnets created for the Region will be displayed. Figure 10.9: List of subnets There is an excellent analogy that can help you understand the relationship between VPCs […]

Application Specification So far, you have specified the AWS resources supporting the deployment (deployment group) and also instructed CodeDeploy on how to deploy the new application release and how to shift traffic to it (deployment configuration). There is one major element left to define, and that’s the application specification to let CodeDeploy know what to […]
